10 Best Fisher Metal Detectors 2025 in the United States

The Fisher Labs XLT30D Liquid Leak Detector is designed primarily for detecting leaks rather than traditional metal detection. This product features a battery-powered operation, making it easy to use in various locations without worrying about power supply. Although it is lightweight at just 0.01 ounces, which enhances portability, the ergonomic design might not be as refined for extended usage periods.

When it comes to the essential specs for metal detection, this model’s operating frequency is tailored for leak detection, so those seeking traditional metal detecting functionalities might find it lacking. The Big Foot and Multi-Sensor features can be beneficial for specific tasks, yet they might not align perfectly with the requirements of traditional metal detector users.

For those looking for a reliable leak detection tool in industrial applications, this product could be an excellent fit. However, enthusiasts or professionals seeking a comprehensive metal detector might need to explore more specialized options that offer robust features such as discrimination, ground balance, and detailed depth indicators. While the Fisher Labs XLT30D can be handy for its intended purpose, it may not meet the expectations of users focused on traditional metal detection.

The Fisher Labs M9711 Metal Detector is designed primarily for locating valves and metal boxes, making it a practical choice for utility workers and hobbyists. One of its standout features is the automatic retune button, which helps maintain optimal sensitivity during use, coupled with a sensitivity selector for fine-tuning detection. With an operating frequency of 4.5kHz, it can effectively detect larger metallic objects, though it may struggle with smaller targets compared to detectors operating at higher frequencies.

The manual ground compensation feature is a plus for users who may encounter varying soil conditions, allowing for better performance in different environments. The 11” search coil provides a decent range, enabling efficient searching over larger areas. An added headphone jack is convenient for private listening, which is great in crowded or noisy locations.

In terms of ergonomics, the M9711 weighs 3.9lbs, which is relatively manageable for extended use, although some users might find it slightly cumbersome over long periods. The adjustable length from 38” to 50” caters well to users of different heights, making it more comfortable for a wider range of people. It has a few drawbacks. The reliance on 2 x 9V batteries may not be the most convenient option for all users, especially considering the battery life of 25 to 35 hours, which may necessitate regular replacements during longer outings. Additionally, while the 4.5kHz frequency is good for certain applications, it may not be versatile enough for users looking to detect a variety of small objects or coins.

The Fisher Labs M9711 is a reliable metal detector for specific tasks like locating valves and boxes, making it suitable for professionals in utilities. For hobbyists or treasure hunters seeking a more versatile device, considering a model with a higher frequency and longer battery life might be beneficial.

The Fisher Labs Gold Bug Pro Metal Detector is a great choice for those interested in finding small gold nuggets, thanks to its high operating frequency of 19kHz, which enhances sensitivity. This feature makes it particularly effective for prospecting in challenging, mineral-rich soils. One standout aspect of this detector is its V-Break Tone Discrimination system, which allows users to distinguish between valuable finds and unwanted trash, enhancing the searching experience.

The Gold Bug Pro also excels in ground balancing, offering real-time adjustments that help maintain accuracy as you move through different terrains. This is particularly useful for beginners who may not have the experience needed to manually adjust settings. The adjustable threshold and gain controls further enhance usability, letting users fine-tune their detection based on specific ground conditions.

A major strength of the Gold Bug Pro is its lightweight design, weighing only 2.5 pounds. This makes it comfortable to use for extended periods, which is ideal for treasure hunters who often spend hours outdoors. Additionally, the user-friendly interface makes it accessible for both beginners and experienced users.
